Driving and controlling method for biomimetic fish and a biomimetic fish

摘要

An aquatic toy that is a biomimetic fish with a watertight body portion. The body portion contains a battery electrically connected via a controller to at least one coil. The coil is positioned relative to a magnet and the coil can be caused to oscillate by virtue of a controller defined alternating current passing through the coil. The oscillation of the coil causes movement of a tail fin that is engaged to said watertight body to cause the fish to move forward through a body of water.

主权项

1. An aquatic toy comprising:
a watertight buoyant body, a propeller dependent from the buoyant body in a manner to be capable of oscillatory motion relative to the buoyant body, the propeller comprises a flexible fin distal from the body and configured to propel the buoyant body through a body of water via a swishing motion of the flexible fin when the propeller is operated an oscillatory motion, and wherein the buoyant body carries:
a) a battery,b) a driver operatively connected to the propeller to cause said propeller to oscillate, the driver being driven by the interaction of an energizable coil through which an alternating current is passed and a magnet, the coil energizable by said battery, wherein either one of the magnet or the coil is directly and rigidly attached to the propeller to cause the propeller to oscillate at the frequency of the alternating current during operation.
